Description:Acanthophysium biapiculatum sp. nov. Fig. 108
Hymenophore annual, ceraceous, arescent, adherent, effused forming elliptical colonies 10-25 mm long, merging to form linear areas to 5 x 1 cm; hymenial surface at first white, becoming cream or alutaceous, even, not creviced; margin thinning out, white, finely fibrillose, adherent. Context white, 60-90 µm thick, basal layer narrow, of mainly parallel hyphae, intermediate layer of scanty erect hyphae, embedding masses of crystals; generative hyphae 2-2.5 µm diameter, walls 0.1 µm, thick, without clamp connections. Dendrophyses scanty, composed of simple stems bearing 2-5 lateral short branches, naked or bearing a few scattered small crystals. Gloeocystidia absent. Hymenial layer to 55 µm deep, a close palisade of basidia, paraphyses, and dendrophyses. Basidia clavate, 24-32 x 10-14 µm, commonly bearing 2 spores, seldom 1 or 4; sterigmata arcuate, stout, to 14 µm long. Paraphyses clavate, 1 6-20 x 5-7 µm. Spores globose or D-shaped, 12-16 x 9-11 µm, with 1 or 2 large apiculi to 3 µm long, walls smooth, hyaline, 0.1 µm 1 µm thick, nonamyloid; often adhering in pairs.
TYPE LOCALITY: Murchison, Nelson, New Zealand.
HABITAT: Effused on bark or decorticated wood of dead branches.
ONAGRACEAE. Fuchsia excorticata: Nelson, Murchison, 170 m, type collection, P.D.D. herbarium, No. 17457.
Spores are subglobose or D-shaped and bear one or two stout apiculi to 3 µm long. They frequently adhere in pairs, when they assume the D-shape. Basidia usually carry two spores, rarely one or four, on long and stout sterigmata. Dendrophyses are composed of simple stems bearing from one to five lateral branches. They rarely exceed 2 µm in diameter, and are commonly naked, a few only bearing scattered fine deciduous crystals.
